Hooking up a cold rad to 80C water

[Onetap]

lets say that water is at 10 or 15 degrees.
1) would that damage the radiator if inject 80 or 90 degree hot water using a high speed pump.

2) Would that make any difference to the time it takes to heat the room

1) No.

That's what happens with old heating systems (look up sundial c-plan); they're still rubbish. Better to start the system earlier at a lower, non-scalding temperature (optimum start).
I've heard that thermal shock (sudden heating) can damage boilers on a multiple boiler installation.

2) Yes, quicker.

But the air temperature is only one factor in what makes a room feel comfortable.

Thanks very much. I will look up Sundial c-plan and thermal shock.

with my idea I think can prevent thermal shock because when heating is called , the boiler doesnt necessarily have to be on. all you need to do it switch on the pump and it will start injecting hot water in the system.

anyway thanks for the info i will list it in the list of potential problems and see how that affects the performance.

How do you intend to heat the water that you intend to pump round the radiators, and how long do you think it will take for your thermal store to become hot?

Answer please.

Is it just me but is this geezer trying to reinvent the wheel but improving it by making it square?

I can't quite bring myself to believe that this thread is for real.

I am going to write to her majesty's patent office and see if I can register a round device capable of rotating and being attached either singularly, or in multiples, to a vessel of unspecified size and configuration. For the purpose of carriage persons or goods from one place to another.

Damn, beat me to it

Hahaha yes If its possible I will go for it. if not me then someone else will ask the same question one day. Im glad we all learned something from this thread.
I believe if you havent tried then do it. you wont get the results that you expect. but you might end up with a totally new product.


Kind Regards

We still have no idea what you think you are trying to achieve.

even I cant believe that someone has never done this

All im trying to do is speed things up.

It was a nice conversation. This was the first time i realised that Internet is such an amazing invention where you can immediately exchange you views with random experts sitting around the world and get your problems sorted out.

Thanks a lot for your help

 

[Corgigrouch]

But it has been done.... You just don't want to listen.

They have. It's about the most primitive control system you can get.

They don't do it now because it's rubbish, only slightly more advanced than an open fire in the middle of the hut with a hole in the roof.

Someone (maybe on Dragons' Den) said they get loads of enthusiastic young entrepreneurs, who insist that there is a gap in the market that their idea will fill. They answer that, there may be a gap in the market, but is there a market in the gap? Usually there are good reasons no-one targets that gap, but the youngster can't see what they are.

PS I think there's something else going on. Is the OP's name an anagram or something?

Forgive me but the whole time the conversation has been about water pushed into a system and temperature raised upto 70 degrees.

can you please name one boiler that does exactly what im trying to achieve

I want to push sudden 80 degrees to a stone cold radiator.

im imagining an average sized radiator getting from 15 to 80 degrees in lets say 10 seconds or slightly more




is there anything that does that??

cheers

All of them.

It won't happen due to the thermal inertia of the radiator, pipes and the water. You could get closer with your thermal store, but there are few advantages and many disadvantages.

Orr something similar.

Is there a catch?
